| 摘 要： | 研究了模与模之间的相互作用对电阻壁模(RWM)稳定性的影响.当存在多个模的相互作用时,最不稳定的(3,1)模的线性增长率有所下降.经过线性演化后,因磁力线在壁上的挤压,电阻壁模进入非线性饱和状态.与单个模的演化相比,多个模存在时,(3,1)模的饱和度会下降,(5,2)模的磁能会有相应的增长,而(2,1)模磁能饱和度变化不大.

| Abstract: | Effects of modes interaction on the resistive wall mode (RWM) stability are studied. When considering the modes interaction effects, the linear growth rate of the most unstable (3, 1) mode decreases. After linear evolution, the RWM saturates at the nonlinear phase. The saturation can be attributed to flux piling up on the resistive wall. When some modes exist, the (3, 1) mode saturates at lower level compared with single mode evolution. Meanwhile, the magnetic energy of the (5, 2) mode increases correspondently, but the magnetic energy saturation level of the (2, 1) mode changes weakly. |
